Abstract

The invention provides a motor and vane-pump set comprising a vane-pump comprising a stator (53) and a rotor (50) fitted with vanes (52) and extended by a shaft (51), with the rotor and stator assembly being disposed in a tank (71) which is partially filled with oil, with the shaft rotating in bearings lubricated by said oil and fitted with sealing rings (61,62), said pump being rotated by an electric motor comprising a stator (44) and a rotor (48) fitted with a shaft (48), the motor and vane-pump set being characterized in that the rotor shafts (48, 51) of the motor and the pump are joined together and in that an envelope (75) of non-magnetic material is disposed between the stator (44) and the rotor (47) of the motor, said envelope being closed at its far end from the pump by a cover (77), and bearing in sealed manner at its opposite end on a motor end plate (76) which is fixed to the pump.
